S4D10120D

Overview

The S4D10120D is a silicon carbide (SiC) Schottky diode array manufactured by SMC Diode Solutions. It features a dual configuration with one pair of common cathodes housed in a TO-247-3 package. The device supports a maximum DC reverse voltage of 1200V and an average rectified current of 5A per diode. Key electrical parameters include a forward voltage of 1.8V at 5A, a peak forward surge current of 46A, and a reverse leakage current of 150µA. It operates within a junction temperature range of -55°C to 175°C.

Feature Summary

• Utilizes silicon carbide technology for ultra-low switching loss and high thermal stability
• Features a dual common cathode configuration suitable for bridge or half-bridge applications
• Provides low total conduction losses with switching speeds independent of operating temperature

Applications

• High-frequency power supply designs
• Uninterruptible power supply (UPS) systems
• DC-DC converter circuits

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm exact pinout compatibility and thermal characteristics. Ensure that the TO-247-3 package dimensions match the target PCB footprint requirements. Confirm RoHS compliance status if required by the end-product regulations. Cross-reference the datasheet revision date to ensure all electrical limits are current.

Selection Notes

Select this component for applications requiring high-voltage blocking capabilities and efficient high-frequency operation. The SiC material offers superior performance over traditional silicon in terms of switching speed and thermal management. Consider the 1200V rating for safety margins in medium-voltage systems. Evaluate the 5A per diode current capacity against the load requirements to prevent thermal overload during continuous operation.
